At any given time, 60% to 85% of prisoners across the United States are struggling with substance addiction and dependence. Upon release, about two-thirds of former prisoners will reoffend and return to prison. Due to the high rate of substance use and abuse in prisons, drug treatment, specifically Correctional Therapeutic...
We use data from a series of small (three to five stations) overlapping magnetovariational (MV) arrays to image variations of vertically integrated electrical conductivity in the crust of southwestern Washington. Two principal structures are revealed: a large north-south trending anomaly (the southern Washington Cascades Conductor (SWCC), which has been detected...
In a companion paper (Egbert et al., this issue) we describe the estimation of very long period (0.16 < T < 91 days) magnetotelluric (MT) impedances from 11 years of data collected at the Tucson geomagnetic observatory. Here we discuss the implications of these data for mantle conductivity. Using minimum...
Although there is increasing evidence that fluids may play a significant
role in the earthquake rupture process, direct observation of fluids in active fault
zones remains difficult. Since the presence of an electrically conducting fluid, such
as saline pore water, strongly influences the overall conductivity of crustal rocks,
electrical and...
“A Monument to Jim Crow’: Post-War Racial Liberalism and the Battle Over the Booker T. Washington Black Veterans Hospital” examines the proposed Congressional bill to build a segregated black veterans hospital as a memorial to Booker T. Washington in Franklin County, Virginia. This paper examines the developing ideology of racial...
Eleven years (1932-1942) of electric potential and magnetic measurement at the Tucson observatory
represent a unique very long period magnetotelluric (MT) data set. We report here on a careful reanalysis of this
data using modern processing techniques. We have developed and used novel methods for separating out the
quasi-periodic daily...
Long-period global-scale electromagnetic induction studies of deep Earth conductivity are based almost exclusively on magnetovariational methods and require accurate models of external source spatial structure. We describe approaches to inverting for both the external sources and three-dimensional (3-D) conductivity variations and apply these methods to long-period (T≥1.2 days) geomagnetic observatory...

there is evidence that...
Aggregate piers have been used for centuries, with increasing occurrence in the last few decades.

Recent work in moral philosophy has displayed a renewed interest in ethics and ontology that consider the social constitution of the subject. However, these approaches to ethics, exemplified in Judith Butler’s work in Giving an Account of Oneself, often neglect the problem of antiblackness, which Afro-pessimist scholars argue operates at...
Xylem is nonuniform in its structure and function throughout the plant stem.

Seismically-induced liquefaction represents a major cause of damage to civil infrastructure and can result in significant damage following major earthquakes. Liquefaction can occur when earthquake ground motions raise pore-water pressures in loose, sandy soil, resulting in a substantial decrease of soil strength. Owing to the potential for instability following liquefaction,...
